Be it known that I, Riiw'ro BRIAs'oo, a sub ie lpf fh ne. i 13, r d wYorl't'city, county and State of New York, have wanted certain new anduseful Imi o ashet de ired. H v

further o ect is to provide a turning be compact and simple in peiatioiiso thatthe sheets will be turned quickly and without displacement.

. Referring to the drawing wherein r have:

preferred embodiment of iiij venues, j V v I 7 Fig. 1' 1s a view inelevation of a music standequipped withmy turning" the saline beingsnow-a broken to preserve sp'ace,

Fig,.2 is an enlarged section eases on the-line of Fig; 1,

Fig. 3, is an enlarged bottom view in elevation of the releasing deviceshowing the turning elements in position to be released,

Fig. 4:, is an enlarged section on the line 44 of Fig. 8, and

Fig. 5, is an enlarged section on the line 5-5 of Fig. 2.

Referring more particularly to the drawings, 5 indicates a music holder,held on a standard 6, the holder 5, comprising a suitable back-board 7and ledge 8. The holder is provided at its lower edge with a turningdevice which comprises a base 9 to which are pivotally secured as by astaple 10, a plurality of nested turning elements 11. These turningelements are engaged by suitable levers 12, which are operated by thesprings 13, wound around the shanks of each of said levers 12, to causethe same to have a swinging movement from right to left. The ends of thelevers which are surrounded by the springs are covered by a suitablehousing 14.

The staple 10, upon which the turning elements 11 are pivoted, isfastened in the base member 9. Each of the turning elements 11, isprovided with a sheet engaging portion 15, which has" secured thereto,suitable arms 16 and 17, the member 15 passing adjacent the pivot 01'staple 10, and being secured to its respective turning elements 11. Theends of the levers 12 engage suitable slots in the turning elements. Inorder to provide for the releasing of the turning elements, one at atime, I provide at the right hand end of the base 9, a substantialU-shaped hollow housing 18, in which is supported a vertical lever 19,pivoted at the bottom of the housing as at 20. This lever 19, carriestwoi fingers 21 and 22, which project into the open portion of thehousing anden'gag'ethe flattened ends of the turning elements 11disposed within the housing 19. In a suitable slot 23, is a bell crank2e, having one of its ends resting in said slot, and having its otherend p'ivotally connected to the vertical lever' 19 as at 25, the bellcrank, of course, being pivoted in the housing as at 26-.

in order to rock the vertical lever 19 at its" pivot, I provide anoperating lever 27, e' x t'eriorly of said housing 19, this lever 27being pivotally secured in a projection of haseo thru the medium of apin 28, and being connected to. the lever 19 by a suitable cord or'wire29; The lower end of the lever 27 is engaged by a like cord or wire 30,which engages a cable 31 as at 32, the end of the cable 31 beingconnected to the base 9 through the medium of a spring 33.

This cable 31 passes through a flexible conduit 34 which is in turn heldto the base member 9 by a lock nut 35, which screws on to a threadedtubular member 86, supported by a bracket 37. The cable 31 and itscovering 34 extend to the floor where the end of the covering engages abracket 38, and the cable itself passes through the bracket to engage afoot lever 39, pivoted to said bracket, as at 40. A spring member 11 isdisposed beneath said lever 39, and tends to keep the same in raisedposition, and the lever 27 in forward position, The latter lever isbrought to this position through the medium of a small leaf spring 42,within the housing 18, the leaf spring engaging the lever 19, to causethe same to move forwardly and prevent operation of the turningelements. In order to provide for the disengagement of the turningelements singly, I provide them with flattened ends 13, two of which areadapted to underlie the finger member 22, when the turning elements arein position to the lever 39, will draw the cable 31 to cause pivotalmovements of the levers 27 and 19, the latter causing withdrawal of thefinger 21 to allow the uppermost turning element to swing to itsopposite position to turn the sheet.

The bell crank 24, before referred to, has a movement opposite to thefingers 21 and 22, so that when the fingers are retracted, the end ofthe bell crank 24. is projected. lln the case of three turning elements,the lowermost two will be snapped into position below the finger 22, andsimultaneously with the releasing of the upper one, the central one willbe allowed to move up against the linger 21, and the lower one will beheld by the bell crank 24. hen the central one is released, the bellcrank will permit the lower one to raise against finger 21, and remainin this position until released. Releasing of each of these elementsoccurs singly upon e'ach pressure of the foot lever.

It will be seen therefore, that I have constructed a turningdevice'which is not only simple in operation, but which can bemanufactured cheaply and quickly applied to any music stand in use.

Having described my invention, what I claim is:

1. A sheet turning device comprising a pintle, a plurality of turningelements mounted on said pintle longitudinally thereof and in pivotalrelation thereto, a housing, a plurality of levers pivotally mounted insaid housing and individually associated with said turning elements tooperate them, individual springs for operating said levers,

each of said turning elements having a flattened portion at one endthereof, and means for securing said turning elements against operationby said levers and for releasing said turning elements for operation bysaid levers comprising a lever having fingers for engaging the flattenedportions of some of said turning elements, a lever for engaging theflattened portions when the lever fingers are withdrawn, and means foroperating said levers simultaneously.

2. A sheet turning device comprising a plurality of turning elementspivotally mounted, individual operating levers for said turningelements, individual springs for said operating levers, means forreleasably securing said turning elements against operation by saidspring actuated operating levers and for releasing said turning elementsone at a time, comprising a lever having a plurality of fingers forengaging a plurality of said turning elements, a bell crank leverpivotally connected to said lever and operated thereby to engage aturning element when the lever is operated to with draw the fingers fromengagement with the turning elements, ,and means for operating saidsecuring and releasing levers comprising a lever pivoted. intermediateits length, a rod connecting said last mentioned lever with said firstmentioned securing and releasing lever, and a rod for operating saidlast mentioned lever.

In testimony whereof I hereunto afiix my signature.

REMO BRIASCO.
